GAUGE.

Application filed September 17, 1924. Seria1 No. 738,253.

This invention relates to a gauge designed primar-ily for indicating visually the amount of oil or gasoline or other liquid contained in a container or containers at points remote from the gauge. The invent-ion is particuklarly designed for use in connection with automobiles, marine engines, andy the like and alfordsa simple and eficient means for indicating accurately the supplies of oil and gas in the respective containers.

A further object is to provide a device of this character which can be installed readily and has no mechanical parts to get out of order.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details ofconstruction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed may be made within the scope of what is claimed without departing from the spirit of the invention.

In the vaccompanying drawings the preferred form of the invention has been shown.l

In said drawings- A Figure 1 is a view partly in elevation and partly in section of the gauge, containers and connections therebetween.

Fig. 2 is an enlarged front elevation of the gauge. Y

Fig. 3 is a section on line 3-3, Fig. 2.

Fig. 4 is a rear elevation of the gauge.

Fig. 5 is a top plan view thereof.

Referring to the figures by characters of reference 1 designates a block constituting a base provided with a lower forwardly projecting extension 2 and an upper forwardly projecting extension 3. Spaced bores 4 are extended downwardly through the extension 3 and are sufficiently large to permit the downward insertion therethrough of glass tubes 5, the lower ends of which are seated in sockets 6 provided in the top face of the lower extension 2. A washer of cork or the like indicated at 7 is seated in each of the sockets 6 and constitutes a support for one of the tubes. Another washer 8 bears upon the upper end of each tube and is adapted to be clamped thereon by a screw plug 9. A.

vent 10 extends through each screw plug and these vents open through the upper washers into the tubes 5.

Separate bores 11 and 12 are extended upwardly into the base block 1 from the lower end thereof and are closed at their lower ends by suitable plugs 13. The bores 11 communicate through an angular passage 14 with the lower end of one of the tubes 5 while the bore 12 communicates through a similar passage 15 with the lower end of the other tube 5. One end of the bore 14 is preferably closed by a screw plug 14.

A boss 1G is provided on the back of the base block 1 and has separate ports 17 and 18 opening into the upper endsof the bores 11 and 12 respectively. A pipe 19 extends from the port 17 andxcommunicates with the bottom portion of an oil container 20, which, if desired, can be the crank case of an engine. Another pipe 21 opens into the port 18 and extends downwardly into a container 22, which can be the gas tank of an engine. This pipe preferably opens into the tank close to the bottom thereof as shown in Fig. l.' The bores 1l and 12 are preferably partly filled with colored fluids. These fiuids can be of the same or ofdifferent colors and obviously,^the level/of the fluid in each bore and the tube 5 communicating therewith will be maintained normally the same. The pipes 19 and 21 as well as the upper portions of the bores 11 and '12 can contain nothing but air. Thus it will be seen .that under normal conditions when the containers 20 and 22 are' empty the'colored fluids inthe tubes 5 will be maintained at their.

lowest levels. When liquids are poured into the containers 20 and 22 portions thereof the bores 11 and 12. Consequently those portions of the liquids within the tubes 5 will be forced upwardly and will act as indicating means to show accurately the amount of liquid within each container. As the liquids in the container are withdrawn the levels of the colored fluids inthe tubes 5 will lower. Suitable provi-ded on the base lock 1 close tothe tubes for cooperation with the colored fluids to indicate clearly the amounts within the respective containers.

It will be noted thatthe vdevice constituting the present invention canbe read easily at night by the light of the lamp upon the instrument board without the necessityof utilizing the hand as a reflector. It will not catch the clothing because it has a rounded face and corners. The device can be inraduations may be`- stalled readily Without mutilating the car and, by reason of the peculiar mounting of the glass tubes, they are protected` from breakage. It will be noted further that the device is neatin appearance, accurate and prevents loss of liquid by the suction produced by lowering of the liquid in the containers. This latter advantage is due to the fact that the large bores allow bubbling from the glass tubes and, therefore, suction is broken. f

What is claimed is ln a low-pressure gauge the combination with a block having a bore extending thereinto from its lower end, the lower end of the bore constituting a drain outlet, there being a pressure inlet at the upper end of the bore, of a removable plug normally closing the lower end of the bore, rounded extensions upon the upperl and lower portions of the block, there being an opening extending through the upper extension and a recess within the lower extension, said opening and recess being in alinement, said block having a passage for maintaining communication between the lower portion of the bore and the recess within theflower extension, one end of said passage opening through the block, a removable closure for said end, a transparent tube insertable downwardly through the openin in the upper extension to seat the ends of t e tube Within the recess and the opening respectively, a screw plug removably mounted within the opening for holding the tube in position, said plug having a vent therein opening directly into the tube and a colored liquid within the tube and passage and the lower portion of the bore.

In testimony that I claim the foregoing as my own, I have hereto aiixed my signature.
